WITH just 64 days to Brexit, nerves are beginning to jangle audibly not only in London but Brussels too.

It is perhaps a sign of desperation when in our system of constitutional monarchy, someone holds up their finger and suggests the answer to a potential problem is getting HMQ involved.

And so it was the darling of the Brexiteer hardliners, Jacob Rees-Mogg, who piped up to suggest if the Remainers were on the point of preventing a no-deal outcome, the Queen should be called upon to prorogue parliament.

His fear is the amendment to extend the Article 50 process to the year-end - to stop a no-deal outcome - led by Labour’s Yvette Cooper, is gaining traction; on Wednesday afternoon she held “positive” talks with Jeremy Corbyn.

If Labour officially backed it, then it could get through and show Parliament was wresting control of the Brexit process from the executive.

As MPs continued to table amendments to next Tuesday’s indicative vote on Brexit, our old friend Michel Barnier helpfully appeared to say a) there would be no Brussels approval to extend the Article 50 process unless Parliament agreed on a Plan B and b) introducing a time-limit on the backstop was a non-starter as it would render it useless.

Earlier this week, the Prime Minister claimed there was not a parliamentary majority for a People’s Vote; given Mr Corbyn’s position, she could be right. The SNP’s Ian Blackford admitted without the chief comrade on board, the chances of another EU poll are zero.

So, come next Tuesday the options could narrow. If a People’s Vote gets eliminated, so too might Norway-Plus and Canada-Plus. The battleground could be over Ms Cooper’s amendment.

Another proposal to set a sunset clause of December 2021 was also retabled.

The PM is hoping that this gets majority backing, so she can go to Brussels and say if the EU27 wants to avoid a no-deal outcome, it will have to budge on the backstop.

It could be that it will take a whites-of-their-eyes’ moment to get Mr Barnier and his colleagues to give way.
